A central goal of paleoanthropology is understanding the role of ecological change in
hominin evolution. Over the past several decades researchers have expanded the hominin …

Increasing body and brain size constitutes a key macro-evolutionary pattern in the hominin
lineage, yet the mechanisms behind these changes remain debated. Hypothesized drivers …

We review the theoretical foundation for the need for human factors science. Over the past
2.8 million years, humans and tools have co-evolved. However, in the last century …

Stone tools provide some of the best remaining evidence of behavioral change over long
periods, but their cognitive and evolutionary implications remain poorly understood. Here …

Abstract In 1987, Phillip Tobias published a comprehensive anatomical analysis of the
endocasts attributed to Homo habilis, discussing issues dealing with brain size, sulcal …

Alterations in brain size and organization represent some of the most distinctive changes in
the emergence of our species. Yet, there is limited understanding of how genetic factors …

While the human brain is clearly large relative to body size, less is known about the timing of
brain and brain component expansion within primates and the relative magnitude of …

There is controversy around the mechanisms that guided the change in brain shape during
the evolution of modern humans. It has long been held that different cortical areas evolved …

The brains and minds of our human ancestors remain inaccessible for experimental
exploration. Therefore, we reconstructed human cognitive evolution by projecting …

A distinctive trait in primate evolution is the expansion in brain mass. The potential drivers of
this trend and how and whether encephalization influenced diversification dynamics in this …
